INHALEB.

Application filed January 24, 1928.

The object of this invention is to provide a pocket inhaler of simple construction which will be adapted to hold and eucase the supply bottle of liquid and in which the bottle thus encased will serve not only as a valve to offer the desirable resistance tothe airl as it is inspired through the inhaler, but which will also serve to distribute the incoming air around and along the cylindrical inner surio face of the absorbent layer to thus insure thorough impregnation of the air with the liquid inhalant, as more fully hereinafter set forth.

In the drawing- Fig. l is a vertical sectional view of the device complete; Y

Fig. 2 is a view partly in side elevation and partly in vertical section with the cap removed; I

2o Fig. 3 is a transverse sectional view taken on the line 3 3 of Fig. l.

Referring to the drawing annexed by reference-numerals, l designates a cylindrical case or tube having a lining 2 of porous ab- 95 sorbent material extending practically its entire length, the bottom of this tube being provided with a central hole 3 and the top of the tube being open. A cylindrical cap 4 is fitted down over the upper open end of the tube l and is rounded at its upper end to fitk into the nostril, the top end of this cap being provided with a central exit-hole 5. In operation, the inhalation of air through the hole 5 draws air in through hole Sand up through the tubular absorbent lining 2 which., of

course, has been previously wetted with the liquid inhalant. An annular bead 6 on the casing-tube l forms a stop for the cap 4.

The cylindrical lining 2 forms a vertical 4o pocket for the reception of the elongated bottle 7 provided with a removable stopper 8,

which bottle is adapted to contain the liquid.

that is to be applied to the lining from time to time. This bottle is long enough to extend preferably practically to the top of the casing l, so as to contain the fullest amount of liquid possible. The bottle in diameter is slightly less than the interior diameter of the cylindrical lining 2, so that an annular space is 5o provided around the bottle. The bottom of Serial No. 249,057.

the bottle rests over and covers the inlet-hole 3 in the bottom of the casing-tube. After a little of the inhalant is applied to the lining 2, the bottle is corked and replaced, and then,

by inhaling through the hole V5, the air is drawn up through the hole 3 and distributed around the bottle in close contact with the inner face of the lining 2, so as to insure a maximum impregnation of the air with the vapor of the inhalant. The bottle, by resting over the hole 3, serves as a valve to properly retard the incoming air, to thus prevent a too-free passage of the air through the inhaler. With the bottle enclosed in the casing,

a supply of liquid is provided with the device in a convenient way, forming an original, complete package, thereby enabling the supply of liquid to be ship ed in the inhalerl and to have it convenient or use whenever it is desired to put a new supply on the absorbent lining.

In Fig. 2, I show paraffin or other sealing coating applied to the stopper and'neck of the bottle, to thereby prevent evaporation of the inhalant enclosed in the bottle.

Vhat I claim as new is:

l. An inhaler embodying a tube having its upper end open and its bottom provided with ahole and its interior provided with a cylindrical absorbent lining, a nozzle-cap fitted on 30 the. upper open end of said tube and provided with an exit-hole, and a bottle of inhalant liquid enclosed in the vertical cylindrical space within the lining and having a diameter less than the internal diameter of the cylindrical lining.

2. An inhaler in the form of an original package embodying a tube having an open upper end and a hole in its bottom and provided interiorly with an absorbent lining, a removable nozzle-cap for the casing having an exit at its upper end, and a bottle of inhalant liquid enclosed within the aforesaid lining and resting on the bottom of the tube over the opening therein, said bottle having adiameter less than the interior diameter of said lining.

In testimony whereof I hereunto ailix my signature.
